To all whom it may ooncemt;

' Be i known that I, JAcdB CLosz, residing at St. Ansgar, in the county of Mitchell and State of Iowa, have. invented certain new and useful Improvements in Pneumatic Tube Testing and Tire-Carrying Devices, of which the following is a specification.

My invention primarily has for its object to provide a simple, inexpensive, light and serviceable device, ,by means of which leaks in the inner tubes of pneumatic tires may bequickly and conveniently detected.

. Another-object of my invention is to providea device of the foregoing character that may serve the two-fold function of a testing device'and a,tirecarrying case, the same being portable and adapted to be readily car- 'ried onthe tire. holder of an automobile. I

.Generically, theainvention comprises a trough or receptacle made of any suitable material to hold Water or its equivalent, the receptacle being preferably circular, opentopped, and having, preferably, a half round bottom,;to receive the inner tube, the receptacle also having provision to receive the tube valve. i i

The invention further includes thepr'ovision of a suitable tube conforming and confining body designedto restrain the tube in the bottom of the receptacle and prevent burstingwhile the-tube is inflated to detect punctures, and particularly slow leaks which only become noticeable and operative under airpressure too great for 'a non-confined inner tube to stand, by escaping air bubbles through the immersingliquid.

I Subordinately, the invention includes those novel features of construction, combination and arrangement of parts, all of which will be first fully described andthen be specifically pointed out in the appended claims and illustrated in the accompanying drawings, in which i 1 1 Figure 1 is atop plan view of one form of the invention. Fig. 2 is an enlarged cross section on the line 22 of Fig. 1. 3 is an enlarged cross sectional perspective on the line 3-3 of Fig". '1. Fig. 4: is a cross section of a modified form of'the in vention showing how the same may be adaptedas a tire and tube carrying case when not filled with water for testing purposes. Fig. 5 is a top plan view of a portion of a modification showing how the coin fining-and restraining member may be composedbf'variousmaterial. 6 is a de- Specification of Letters Eatent.

tail perspective view illustrating modified way of securing the restraining member in place. Fig. 7 is a detail cross section of a modification designed for the reception. of tubes of difierent wheel diameters. Fig; 8 is a top plan View of a further modification. F g. 9 is a cross section on the line 9-9 of Fig. 8. Fig. 10 is a cross section showing a modification of the form shown. in Fig. Fig. 11 is a cross section showing a further modification of the construction shown in Fig. 8. Fig. 12 is a cross section similar to Fig. 10, showing the same modification designed for a single tube receptacle.

Referring now to the accompanying drawings, inwhich like numerals of refer once designate corresponding parts in all of I the figures, I designates the bottom of the receptacle which, in the preferred form, is

of substantial semi-circular shape cross" section, the receptacle being of a trough-like form and provided with an outer annular upwardly extending wall, 3, and an inner annular outwardly extending wall d being formed to provide a valve receiving recess 2,.as best shown in Figs. 1 and 2 of the draw ings.

The upper edges of the receptacle may be curled over to provide reinforcements, as at 5, if desired. The receptacle referred to may be made of any suitable material and in diiferent sizes as maybe found desirable.

In order to confine the tube within the bottom of the receptacle and prevent its ere pension beyond predetermined limits, I pro vide what I "term, for convenience of description, a tube confining and restraining body 6 which is in the nature of a cover for that portion of the tube'that does not inc ride flexible strip members 10 that may be hinged in any approved way as by an ordinary hinge joint at 11 to the inner wall a of the receptacle and detachably secured to the outer wall 3 by upright strips lQ'that have spring hooks 1.3. These hooks 13 may v, be sprung over the outer head and in order to enable their convenient detachment they may be provided with finger engagements fabric, or wire, a solid body 17 opaque throughout'the greater part of its area and provided with a transparent opening, through which the tube may be viewed, as at 18, (see Fig. 5) or it may be made of canvas, duck, etc., as at19 and provided with either a transparent solid body 18 of mica, glass, or other suitable material, or with a mesh section 20, through which the tube can be ,viewed: It should be understood that when the restraining and confining member is made ofian opaque body withv the same should be made susceptible of shifting rotatably throughout the central axis of the receptacle, so as to expose different parts of the inflated tube in order to locatethe leak.

When the restraining member 6 is to be made wholly removable or made-susceptible of shifting, the fastening devices may be lugs 23 on the walls of the receptacle, as

shown in the detail Fig; 6.

In Fig. 7 I have shown a further modification in which the trough'or receptacle is designed to receive a plurality of tubes of different wheel diameters and in this form,

the-bottom 33 is formed of two semi-cylindrical tube receiving portions.

A cover 29 may be provided to close the open side of the receptacle and this is partieularly advantageous when the receptatcie is to be used also as a spare tire case (see Fig. 4). By reference to Fig. 4, it will be noticed that the cover 29 may be riveted or otherwise secured to the inner wall of the receptacle at 30 and fasten to the outer wall by snap fasteners 31. or in any other suitable way. In the formshown in Fig. 4, the bottom 1 merges at 26 with an enlarged or extended portion 27 that is adapted to form the receiving pocket vfor the spare tire 32.

In Fig. 8, I have shown a further modification in which the receptacle is in the nature of a pan in which removable restraining and immersing bodies 34-35 may be located, the removable bodies 34-35 consisting of two half sections preferably provided with interprojecting beads 36 to afford a complete closure and prevent the tube from pinching, the restraining bodies 3 l-.35 being held in place, to maintain the tube or tubes immersed, by suitable lugs 37 on the walls of the receptatcle that are adapted to be engaged by locking projections 38 which are carried by the upper section 35 of the restraining member, it being understood, of course, that the restraining member in this form may be constructed of any desired materials, as in the other forms, and may be adapted to receive a tire of a'single wheel diameter size, as indicated in Fig. 10, or may be made to receive a plurality of tubes at the same time, as shown in Figs. 8 and 9.

In the form shownin Fig. 11, the confining and restraining member may consist of a channeled body 39 (either single or double) having an opening along one side and adapted to be -snugly held againt the a transparent bddy 18 or mesh window 20,

bottom of the receptacle 40 by the lugs 37 as indicated in Fig. 11 of the drawings.

It should be understood that the restraining member 6 when made of mesh material may be composed of a semi-rigid, rigid or flexible mesh body, depending upon the materials used, it being understood, however, that the materials employed should be of sufficient strength to serve the desired pur-'' pose, and when a transparency 18 is used, the same may be composed of glass, mica etc. It will also be observed by the use 0% my inventionyslow leaks and punctures in "pneumatic tires can bereadily determined and as the device is constructed, the tube may be reversed in the receptacle as often as desired, in order to ex-posethe entire surface of the same to view in the water to enable the detection of leaks by the air bubbles formed.

While I have shown several modifications of the invention, I do not wish it understood that I limit. myself thereto, as other moditications in the details of construction and design of the parts will readilyoccur to those skilled in the art.

In a device of the character stated, a receptacle adapted to receive a liquid and adapted to receive atire tube when inflated, and a body coiiperative with the receptacle -for confining the. tube against bursting, said body adapted to permit the escape of air tocreate bubbles in the liquid and thereby locate punctures and leaks.
